This Grade 4 Science worksheet challenges learners to trace full energy transformations in real devices and situations. Four multiple-choice items examine battery toys, hairdryers, rubber bands, and flashlights, while five fill-in questions cover windmills, friction, solar panels, microwaves, and conservation of energy. Hints and clear explanations help Grade 4 students follow each energy chain from one form to another and apply NGSS 4-PS3 ideas to familiar objects.
Style:
Energy: Forms and Transfer
Part A: Multiple Choice
Circle the best answer for each question.
1. A battery-powered toy car rolls across the floor. Which energy chain best describes what happens?
A) Chemical to electrical to motion energy
B) Light to sound to heat energy
C) Sound to chemical to electrical energy
D) Heat to light to chemical energy
2. When a hairdryer is turned on, what two forms of energy come out of it?
A) Chemical and light
B) Motion and heat
C) Sound and chemical
D) Light and chemical
3. A child stretches a rubber band and then lets it go to launch a small paper ball. Which transformation is happening when the band snaps back?
A) Light energy to sound energy
B) Heat energy to chemical energy
C) Potential energy to kinetic energy
D) Electrical energy to potential energy
4. A flashlight is turned on in a dark room. Which energy change happens first inside the flashlight?
A) Light energy changes into electrical energy
B) Chemical energy in the battery changes into electrical energy
C) Sound energy changes into light energy
D) Heat energy changes into chemical energy
Part B: Fill in the Blank
Write the correct answer on each line.
1. A windmill turns wind's motion energy into electrical energy that powers homes.
2. When a moving ball slows down because of friction, much of its kinetic energy is changed into heat energy.
3. A solar panel changes light energy from the Sun into electrical energy.
4. A microwave oven uses electrical energy to make food gain heat energy so it warms up.
5. Energy is never made or destroyed; it is only transformed from one form to another.
